Author:Dudley, Angela L; Milione, G; Alfano, RR; Forbes, ADate:2014We present a new all-digital technique to extract the wavefront of a structured light beam. Our method employs non-homogeneous polarization optics together with dynamic, digital holograms written to a spatial light modulator to measure the ...Read more
Author:Schulze, C; Naidoo, Darryl; Flamm, D; Schmidt, OA; Forbes, A; Duparr, MDate:Aug 2012We propose a new method to determine the wavefront of a laser beam based on modal decomposition by computer-generated holograms. The hologram is encoded with a transmission function suitable for measuring the amplitudes and phases of the modes ...Read more
